EnglishCocuy de penca is an indigenous alcoholic beverage of the Venezuelan territory, produced from the Agave Cocui Trelease plant and considered as natural, ancestral and cultural heritage of the nation, being a distillate that has gained relevance in the market in recent years due to their particular sensory characteristics. The purpose of the research was to establish the organoleptic properties of the Cocuy de Penca produced in Lara. For this, eight samples from different parishes were selected; subsequently, the study had the following order: definition of the sensory descriptors, construction of the survey, selection of the panel of juries, conditioning of the environment for the tasting, preparation of the samples and, finally, sensory analysis. Obtaining that the organoleptic profile of the samples of Cocuy larense make it up two descriptors for visual analysis, twenty for olfactory and eighteen for gustatory.","PeriodicalId":359194,"journal":{"name":"Publicaciones en Ciencias y Tecnología","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129903924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

EnglishSensory evaluation for the food industry is a key activity in the development of products that allows us to know the expectations and needs of consumers; therefore, applying sensory tests allows us to build a profile of a winning cereal in the market. This research presents an analysis of various sensory testing methods applied in the manufacturing of wheat-based infant cereals in Venezuela. A sample of twelve companies and a sensory panel of forty consumers were used. A comparative study was carried out between the discriminatory, affective and descriptive sensory tests; in addition to a correlation between the type of test used and consumer acceptance, using descriptive statistical analysis. Affective tests occupy 42% of application in companies nationwide, 32% use discriminatory tests and 26% correspond to descriptive tests. By correlating the test type and consumer acceptance, it was found that companies that use discriminatory, affective and descriptive tests obtain a product that meets consumer expectations, and as they stop applying these tests, the products are less attractive for the consumer.

Como resultado se tiene que apenas un 0,43% del total de vias son para la circulacion de ciclistas y peatones; el autobus es el principal modo de transporte; la mayor cantidad de viajes diarios son realizados en transporte publico, el mayor consumo energetico y emision de CO2 es atribuido al transporte individual y el 69% de los accidentes provocados por transporte ocurren en entornos urbanos.

EnglishLatin American cities have spread in the last three decades causing greater need for mobility and transportation of masses of people, being a pillar in the economic and social development of the main cities; however they bring with them negative effects. The present work identifies and describes these negative effects on society and the environment in Latin American countries, through a descriptive-documentary work, supported by the literature review on mobility and transport systems of the main Latin American cities, in addition to the review of data published by OLADE, WHO and CAF for each unwanted effect to consider. As a result, only 0.43% of the total roads are for the circulation of cyclists and pedestrians; the bus is the main mode of transportation; the largest numbers of daily trips are made by public transport, the highest energy consumption and CO2 emission is attributed to individual transport, and 69% of transport accidents occur in urban settings. The subway is the one with least negative social and environmental impact. The high death rates from road accidents and high consumption of electrical energy represent the most important impacts caused by public transport systems.","PeriodicalId":359194,"journal":{"name":"Publicaciones en Ciencias y Tecnología","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130630976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
